Embodiment Construction

[0011] Such as Figure 1-3 As shown, the light-emitting diode lamp of a preferred embodiment of the present invention can be used for indoor or outdoor lighting in places such as squares, streets, and roads. The LED lamp includes a lampshade 10 , a plurality of heat sinks 20 attached to the lampshade 10 , a plurality of strip-shaped LED modules 30 attached to the inner surface of the lampshade 10 and an adjusting device 100 disposed in the lampshade 10 .

[0012] The lampshade 10 is used for conductively combining with a lamp holder (not shown in the figure) and at the same time fixing the entire LED lamp to the lamp holder. The lampshade 10 is an umbrella structure, which is usually made of transparent plastic, glass or other materials. The lampshade 10 is provided with several triangular notches 12 along its circumference, and the notches 12 evenly divide the umbrella-shaped lampshade 10 into several fan pieces (not shown in the figure), and a circular perforation 14 is pro...

Abstract

The invention relates to a light emitting diode lamp which comprises a lamp cover, a plurality of radiating fins and a plurality of light emitting diode modules, wherein the radiating fins are disposed on the outer wall surface of the lamp cover, and the light emitting diode modules are attached to the inner wall surface of the lamp cover. The lamp cover comprises a plurality of pins connected toone end; and an adjusting device is connected with the end where the pins are connected, and the adjusting device is further connected with the inner surface of each pin movably. When the adjusting device is adjusted, the pins rotate around the end where the pins are connected to enable the side walls of the adjacent pins to approach or separate. The illumination range and the illumination brightness of the light emitting diode modules which are attached to the inner wall surface of the lamp cover can be adjusted according to practical situations by using the adjusting device which is installed on the inner wall surface of the lamp cover to exert the utilization efficiency of the light emitting diode lamp to the maximum extent, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to a lighting device, in particular to a light-emitting diode lamp capable of adjusting the illumination range and illumination brightness. Background technique [0002] As an emerging third-generation light source, although it cannot replace traditional incandescent lamps on a large scale, it has the advantages of long working life, energy saving, and environmental protection, and is generally favored by the market. Moreover, the current modules composed of light-emitting diodes can produce high-power, high-brightness light sources, which can completely replace existing incandescent lamps for indoor and outdoor lighting, and will also widely and revolutionaryly replace existing light sources such as traditional incandescent lamps. And then become the main light source in line with the theme of energy saving and environmental protection. [0003] However, neither the illumination range nor the illumination brightness of the exist...
